Is somewhat high inflation a net good for the U.S. longterm?

Question

I understand that economics is a rather complex subject and this isn't exactly the place for a non-technical discussion, but I greatly enjoy the insights of the HN crowd so thought I'd post this. In July of 2021 I had an interesting conversation with a former investment banker about economics and he made the claim that inflation would be necessary for the U.S. to basically inflate away a good portion of its debt (and of course, erode the savings of dollar holders at the same time). Given U.S. debt levels and still relatively high employment levels domestically, could high(ish) inflation in the U.S. be a net good? I understand the dramatic ramifications on prices for things like homes, but maybe in the end a little pain in that area means that local/state govts will finally engage in permitting reform and help bring down prices in other ways.

I've no idea of economics. But I lived in a country where for a decade we had deflation. Let me tell you: not a good thing! At the beginning, seems good, each time you buy something, is cheaper as before... but that has the down side: people start to speculate: they do not buy what they need, they wait until the very last moment. Moreover, the money in the bank, is a good thing, each time it is more value... so "don't spend". May seem a little thing, but when the whole economy goes in that train, it starts to stop everything, which in turn makes more deflation... you get the idea.
It was explained to me, at that time, that a little bit of inflation is a good thing, and keeps the wheel turning.
Maybe somebody who really knows about economics may laugh...
